(The numbers at the beginning of the Bill of Material are resistors. Just using only numbers for a better readabilty in the layout.
I used a TL074 instead of the LF444. All diodes are 1N4148.)
Edit: Q1 need to be turned by 180 degrees.

I checked it three times and couldn´t find a mistake,
but today I connected it to the resistor chain to calibrate it
and couldn´t get anywhere near the 0.3959V.
Instead I get voltages from 2.8V till 3.52V, depending on the adjustment of the Trim Pot R3.
Help please!!!
Thank you!!!
